VACUUM CLEANER.

Application filed December 26, 1924. Serial lid 758,030.

This invention relates to vacuum cleaners, and the object of theinvention is to provide a vacuum cleaner which combines the advantagesof suction cleaning with the brushing or sweeping .action of a carpetsweeper.

Another object of the invention 1s to provide a vacuum cleaner having arotatable brush in which the brush is rotated by the wheels on which thevacuum cleaner casing is mounted. 1 I A further object of the inventionis to provide a vacuum cleaner in which all parts are easily removablefor repairing and cleaning. p

Another object of the invention is to provide a vacuum cleaner in whichthe usual suction opening may be closed to allow the various cleaningattachments to be connected to an additional opening provided therefor.

I These objects and the several novel features of the invention arehereinafter more fully described and claimed, and the preferred form ofconstruction by which these =objects are attained is shown in the accom2 panying drawings in which- Fig. 1 is a partial section of the forwardend of a vacuum cleaner embodying my invention.

Fig. 2 is an elevation of the vacuum 30 cleaner.

Fi 3 is a view of the mouth of the vacuum c eaner.

Fig. 4 is an endv view of the vacuum cleaner. :5 Fig. 5 is a sideelevation of the roller and brush mounting for the vacuum cleaner.

Fi 6 is a perspective view of the strip for c osing the mouth of thevacuum cleaner. As shown in Fig. 1 the vacuum cleaner is provided'withan electric motor enclosed in a casing 1., The shaft 2 of the electricmotor is provided with a fan 3 on the end thereof. The electric motor 1is positioned in the easing 4 and is provided with a band 5 securedthereto and havin apertures 6 therein for the screws 7 by whlch thecasing is attached to the motor. The motor is supported within thecasing on the lugs 8 shown in Fig. 1 so a space or conduit 9 isprovidedbetween removal the brush 13 may be easily remov the motor and thecasing. The casing 4 as if desired. As shown in Fig. 6 a way 14 isprovided in the slide ll into which an additional slide 15 may beinserted for closing the opening 12. At this time by unscrewing the plug16 shown in Fig. 4 the different attachments for cleaning walls,furniture etc., may be threaded into the casing 4 and the air and dustmay be drawn through the attachment and through the casing '4 into thebag 17. Each end of the casin 4 is enlarged as shown in Fig. 3 and abracket 18 may be positioned in each enlarged end with the studs 19extending through the casing'4 onto which the nuts 20 may be threadedfor holding the brackets 18 in place. Each bracket 18 carries two smallwheels 21 preferably provided with rubber tires 22 and these wheels 21project slightly below the lower face of the casmg 4 so that the casinis supported slightly above the surface 0 the floor. The brush 13 isrotatably mounted at each end in the brackets 18 and is provided with aroller 23 at each end contacted by the rubber tires 22 of the wheels 21.By this arrangement as the vacuum cleaner is moved over the floor thewheels are rotated and rotate the brush 13 through contact with therollers 23. It will be noted from Fig. 2 that the slide 11 fits betweenthe wheels 21 and the bristles of the brush 13 extend through the slot12 in the slide 11 in order to contact the surface being cleaned. Thebag 17 is attached to the casing 4 by means of a collar 24 and the wires25 for the electric motor are carried through the handle 26 of thevacuum cleaner to a switch 27 for controlling the motor circuit. Thebandle 26 is pivotally connected to opposite sides of the casin 4 at thepoints 28 and the casing is mounte wheel 29.

at the rear on a pivoted When the switch 27 is closed, as shown indotted lines in Fig. 2, the motor drives" the fan 3 which draws air intothe slot 12 and through the space or conduit 9 in the casing 4 fromwhich the air is blown into the bag 17 and any dirt carried by the aircurrent remains in the bag. about the rotating wheels 21 rotatethe-brush 13 and thus the surface being cleaned is swept and theloosened dirt is drawn into the cleaner. By closing the opening 12 withthe slide 15 the attachments may be connected by removing the plu 16 sothat the szir is drawn directly throug the attachmen As the cleaner ismoved From the foregoing description it becomes evident that the deviceis very simple and efficient in operation, will not easily get out oforder, is composed conse uent low manufacturing cost, and provi es adevice which accomplishes the objects described.

Having thus fully described my invention, its utility and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States is 1. A vacuum cleaner comprising a substantiallycylindrical casing having an opening at its forward end and a dischargebpening at the rear end, a nozzle at the forward end below the saidforward opening, an electric motor having a shell mounted in the saidforward opening of the casing closing the same and positioned in spacedrelation with the bottom wall and rear end of the casing providing inconjunction therew'itha channel extending from the nozzle to the saiddischarge opening, and a fan in the said channel at the rear endofthemotor shell forward of the discharge opening and operatively-connectedwith the motor.

2. A vacuum cleaner comprising a substantially cylindrical main casinghaving an opening at the front end, eccentric to the axis of the casing,said casing also having a discharge opening at the rear end, a nozzleportion provided at the forward end of the casing below the said frontopening greater of few parts and is of 0 in width than the diameter ofthe casing and having a downwardly opening slot for in ess of air, amotor having a substantially y indrical casing in the said front openingof the main casing and closing the same, the eccentricity of the motorcaslng relative to the main casing providing a space at the bottomtherebetween, a fan at the forward end of the motor between the motorcasing and the rear of the main casing, and roller supports for the maincasing.

i 3. In a vacuum cleaner, a main casing having a nozzle portion at itsforward end,

the said nozzle portion having a width greater than that of the casingand being provided with a slot in its lower face extendinglongitudinally thereof, a brush member mounted in the said nozzleportion, the width of 'the said slot permitting introduction and removalof the said brush, a plate for closing the said slot and having-acentral opening extending longitudinally of said plate permitting thebrush fibers to extend beyond the plate, and a slide for closing thecentral.

opening of the said plate, the said nozzle portion having an openingabove the lower face thereof adapted for the attachment of the hosemember, and a plug for sealing the said opening when not in use.

In testimony tion.

whereof, I sign this specifica- DAVID U. REMALEY.
